Networking

Modern networks like the Internet — explained as simply as possible — but no simpler.

Understand wireless from first principles — seven domains, forty original diagrams, and ten real-world field scenarios that turn exam facts into engineering instinct.

Build secure, modern infrastructure with confidence. This hands-on guide shows you how to use Tailscale, WireGuard and zero-trust networking to create reliable, observable systems that scale. Follow practical, production-ready examples you can apply right away without guesswork or unnecessary complexity.

Learn Python as a network engineer, not as a computer science student. 632 pages, every example built on real device output. Cisco-first, with Juniper and Fortinet.

Most network automation books stop at "here is a playbook that configures a VLAN." This one keeps going — through data models that survive their second year, rollouts that stop at the first device instead of the four hundredth, and the discipline that turns a repository of clever playbooks into something your colleague can run while you are on holiday.

Studying to get your Juniper JNCIE-ENT, JNCIP-ENT, or just looking to really learn Junos? If so, then this workbook may be a great resource for you. This guide is the culmination of my study notes, notes and input from others as well as our collective experiences.  Ultimately it is what I used to pass my JNCIE-ENT exam.  

You know how to code, but everyone else seems to "just get it" while you secretly Google and ChatGPT everything. The Software Realm DECODED is the patient mentor conversation you've been searching for, Peter asks the questions you're afraid to ask, and the Ultra Senior Developer explains what bootcamps skip and seniors assume you know. By the final chapter, the imposter syndrome disappears and systems finally make sense.

From the fundamentals of TCP/IP to advanced packet manipulation and analysis techniques, we have delved deeply into the core concepts that power modern networks. The practical examples and hands-on approach were created to teach you real-world skills that you can immediately apply to your projects. Whether you're developing network applications, troubleshooting network issues, or automating network tasks, the knowledge in this book will help you succeed.

The book then guides readers through Virtual Private Networks (VPNs), detailing their importance, functioning, and distinct types of VPNs. It explores wireless networking and asynchronous programming, providing clear illustrations of WiFi, Bluetooth, and Zigbee setup using C++. It covers critical wireless standards and security protocols.

Read a book, do some labs and take the exam!

Build real-world software by coding a Redis server from scratch.Network programming. The next level of programming is programming for multiple machines. Think HTTP servers, RPCs, databases, distributed systems.Data structures. Redis is the best example of applying data structures to real-world problems. Why stop at theoretical, textbook-level knowledge when you can learn from production software?Low-level C. C was, is, and will be widely used for systems programming and infrastructure software. It’s a gateway to many low-level projects.From scratch. A quote from Richard Feynman: “What I cannot create, I do not understand”. You should test your learning with real-world projects!

Everything you need to pass the 300-215 DFIR exam — all five domains, 18 original diagrams, and 159 practice questions — in one clear, unofficial study guide.

The structured, hands-on study guide that gets you through CBRCOR 350-201 — and actually good at the job: full blueprint coverage, 145 explained questions, runnable labs, and real case studies.

Cloud networks rarely fail in obvious ways. A DNS lookup breaks, a route disappears or traffic vanishes somewhere between clouds. This book shows you how to understand what is really happening, build networks that hold up under pressure and troubleshoot failures with confidence across AWS, Azure, Google Cloud, Kubernetes and hybrid environments.

What really happens when you open a website, send a message or connect to a server across the world? This book builds the Internet from first principles, revealing how bits become packets, packets cross networks and protocols make it all work. Learn the machinery behind the Internet by understanding why each piece exists and how it fits together.
